An organization recently faced a cyberattack where an attacker captured legitimate user credentials and gained access to the critical information systems. He also led other malicious hackers in gaining access to the information systems. To defend and prevent such attacks in future, the organization has decided to route all the incoming and outgoing network traffic through a centralized access proxy apart from validating user credentials. Which of the following defensive mechanisms the organization is trying to strengthen?

SQL Map- Automated SQL injection tool

-
Image
    SQLMap is an open-source penetration testing tool that automates the process of detecting and exploiting SQL injection vulnerabilities in web applications. It is written in Python and is available on Linux, Windows, and macOS. SQLMap is a powerful tool that can be used by security professionals, penetration testers, and ethical hackers to identify and exploit SQL injection vulnerabilities in web applications. SQL injection is a type of security vulnerability that allows an attacker to manipulate a web application's SQL database by injecting malicious SQL statements into an entry field, such as a search field or a login form. This can lead to data theft, data manipulation, and even complete control of the web application and its underlying database. SQLMap works by sending various SQL injection techniques to the targeted web application to identify vulnerabilities. It supports a wide range of database management systems such as MySQL, Oracle, Postg...

Red Teaming - A comprehensive approach

-
Image
        Red teaming is a comprehensive and systematic approach to testing the security of an organization's systems, networks, and physical facilities. It is a proactive approach that helps organizations identify and mitigate potential security risks by simulating real-world attack scenarios. The objective of red teaming is to identify vulnerabilities, weaknesses, and gaps in an organization's security posture and to help the organization improve its security defenses. Red teaming typically involves a team of experienced security professionals who are given the task of testing an organization's security. These professionals use a variety of techniques, tools, and methodologies to simulate different types of attacks, including social engineering, physical security breaches, network and application attacks, and other methods commonly used by hackers and other threat actors. The goal of a red team is to replicate the tactics, techniques, and procedures of...

You have compromised a server on a network and successfully opened a shell. You aimed to identify all operating systems running on the network. However, as you attempt to fingerprint all machines in the network using the nmap syntax below, it is not going through. invictus@victim_server:~$ nmap -T4 -O 10.10.0.0/24 TCP/IP fingerprinting (for OS scan) xxxxxxx xxxxxx xxxxxxxxx. QUITTING! What seems to be wrong?

QUITTING! What seems to be wrong?   A. OS Scan requires root privileges. B. The nmap syntax is wrong. C. This is a common behavior for a corrupted nmap application. D. The outgoing TCP/IP fingerprinting is blocked by the host firewall.
